NETWORK CONNECTION OPTIONS
You can connect the device to the network by either using a WiFi 2.4 GHz
connection or a network cable.
OPTION 1
Network cable (recommended, maintenance free)
Install a network cable (which is plugged into a network switch / router
with Internet access) from the inside of your building to the assembly
location. The network cable between the assembly location and the
network switch / router can have a maximum length of 80 m/262 ft (IEEE
802.3). If you must span a distance of more than 80 meters/262 feet you
can put a network switch in between. Make sure to use a high-quality
Cat.5 network cable or better and with proper shielding (Screened Foiled
Twisted Pair (S/FTP or SFTP)) whereby the shield is connected to the outer
metal shield of the RJ45 plug (8P8C).
The device itself does not have an RJ45 socket. The scope of delivery
includes an RJ45 adapter that can be routed out of the housing. As an
alternative, the RJ45 connector of the network cable can be removed
on the device side to connect the wires directly to the Phoenix strip
according to the assignment under point 7 „CONNECTING THE DEVICE".
OPTION 2
WiFI 2.4 GHz
When using WiFi please make sure you have a good WiFi signal at the
assembly location of the device. You can increase the WiFi signal by using
so called "WiFi repeaters", which can boost your WiFi signal. You should
install such a WiFi repeater close to the assembly location of the device,
typically inside your home and close to the device.

PREPARE POWER SUPPLY
The device does not have a battery as power supply, therefore, choose one
of the following options.
OPTION 1
Power supply using the power supply unit (mains adapter)
To power the device using the provided mains adapter, 2 insulated wires
are required. The power supply unit has a 300 cm (9.8 ft) long cable with
two insulated wires. The network connection is then established via a
network cable or alternatively via WiFi.
Do not plug the power supply unit into the wall socket yet.
NOT IC E
Only use the power supply unit provided along with the device,
or a DIN-rail power supply unit (see "OPTION 3") that you
can obtain from us separately, since this has been specially
stabilized electrically and is equipped with an integrated audio
interference reduction device. Other power supply units may
destroy the device or cause poor transmission quality. The
warranty automatically expires if you use a different power
supply unit.
If you have only two wires available at
the assembly location, you may use the
"DoorBird 2-Wire Ethernet PoE Converter
A1071", sold separately. It allows you to
transfer network data (Ethernet) and
power (PoE) with a simple two-wire
cable over long distances. For example,
existing buildings with a simple two-wire
bell wire can be equipped with network
technology without having to retrofit any
network cables.
For reasons of network stability, we
principally recommend using a network
cable, as WiFi is sensitive to interference
(range, house walls acting as shields, re-
liability of performance, third party WiFi
networks, wireless transmitters causing
interference in the area, etc.).
The provided mains adapter is only
capable to power one device. It is not
designed to power multiple devices
simultanously.
If you must power more than one device
with one power supply, we recommend
to use a PoE-Switch with PoE Standard
IEEE 802.3af Mode A or an appropriate
DIN rail power supply (see "OPTION 3").
